National Institute of Building Sciences

The National Institute of Building Sciences (NIBS) is a non-profit, non-governmental organization established by the U.S. Congress in 1974. Its core mission is to serve the public interest by advancing building science and technology to improve the built environment, fostering a safer, more resilient, and technologically advanced infrastructure for American communities. NIBS connects research, policy, and practical application, acting as an authoritative source for findings and recommendations that impact the built environment. The organization is headquartered in Washington, D.C.

NIBS provides a range of services, including the development and refinement of industry standards such as the National BIM Standard-United States® (NBIMS-US™) and the United States National CAD Standard® (NCS). It also acts as a steward for comprehensive resources like the Whole Building Design Guide (WBDG) and the SF Tool, which are freely available to the public. The Institute offers expertise in facilities planning, design, construction, building codes, disaster resilience, and real property asset management, serving government agencies, building professionals, policymakers, and owners.

Under the leadership of President and CEO George K. Guszcza, NIBS continues to address critical industry challenges. Recent initiatives include leadership promotions in early 2026 to strengthen federal and infrastructure programs, and the appointment of a Chief Growth Officer. In 2025, NIBS co-hosted the "Elevate 2025" summit to tackle the workforce shortage in the built environment and released reports on Building Information Modeling (BIM) and sustainable facilities. The organization maintains a focus on advancing building innovation, enhancing lifeline infrastructure, and promoting the adoption of emerging technologies.
